PTL Duplicated homeodomain-like superfamily protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: PTL
Official Full Name: Duplicated homeodomain-like superfamily protein
Primary source: TAIR:AT5G03680
Locus tag: AT5G03680
See related: Araport:AT5G03680
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F17C15.100; F17C15_100; PETAL LOSS
Summary: Recessive mutations are defective in organ initiation and orientation in the second whorl. This gene encodes a trihelix transcription factor whose expression is limited to margins of floral and vegetative organs. Overexpression and double mutant analyses suggest that this gene is involved in limiting lateral growth of organs.

PTL interacts with AKIN10 in Arabidopsis.
Title: PETAL LOSS, a trihelix transcription factor that represses growth in Arabidopsis thaliana, binds the energy-sensing SnRK1 kinase AKIN10.
Loss of PTL function disrupts auxin dynamics, allowing the role of auxin in promoting petal initiation to be revealed.
Title: Auxin controls petal initiation in Arabidopsis.
restrains the size of the inter-sepal zone during early flower development
Title: PETAL LOSS is a boundary gene that inhibits growth between developing sepals in Arabidopsis thaliana.
Data suggest that accurate temporal and spatial expression of PTL is essential for its proper functional implementation during plant development.
Title: A gain-of-function mutation of transcriptional factor PTL results in curly leaves, dwarfism and male sterility by affecting auxin homeostasis.
